# TrollBridge Cron-Watch — Silent-Death Risk Analyzer

> TrollBridge Cron-Watch — Silent-Death Risk Analyzer is a paid API for AI agents from mini-tollbooth.onrender.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Analyzes submitted scheduled-job history to detect stale or silently-failing cron jobs, returning gap analysis, staleness flags, and a SILENT_DEATH_RISK score per job with recommended remediation checks.

## Facts

- Endpoint: GET https://mini-tollbooth.onrender.com/cron-watch?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/trollbridge-cron-watch-silent-death-risk-analyzer-e59ad491

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability trollbridge-cron-watch-silent-death-risk-analyzer-e59ad491
```

Example prompt: Can you check my scheduled agent jobs for silent failures? I have a 'daily-brief' job that runs daily and a 'price-sync' job that runs every 15 minutes — here are their last run timestamps and last successful run times. Give me a SILENT_DEATH_RISK score and flag any stale ones.

## When to prefer this

Use this endpoint when you need a stateless, per-call audit of scheduled job health without setting up persistent monitoring infrastructure. Ideal for AI agents that manage their own cron pipelines and need to self-diagnose silent failures before or after a deployment. Prefer this over full observability platforms when you want a lightweight, pay-per-call risk score with no long-term data retention.

## Known failure modes

- Missing or malformed 'jobs' query parameter returns an error — the parameter must be a URL-encoded JSON array
- Invalid cadence values (not '15m', 'hourly', 'daily', or integer seconds) may cause parsing failures
- Missing required fields (name, cadence, last_runs) in job objects will cause incomplete analysis
- Empty last_runs array may result in worst-case risk scores with no gap data
- Payment not included or insufficient USDC ($0.05 required via x402) results in 402 Payment Required

## How this service works

The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged.

## Output

A JSON response containing per-job analysis: staleness status (e.g. 'stale'), number of missed windows, next expected run timestamp, a SILENT_DEATH_RISK score (0-100), staleness multiple, and an array of recommended checks. Also includes a lane identifier, a human-readable summary, and count of jobs analyzed. Analysis is stateless — based solely on the submitted history.
